Upgrade to Quantitative Westerns
Direct infrared fluorescence detection on the Odyssey
Infrared Imaging System provides the established standard
for Western blot analysis that can’t be equaled with chemiluminescence and visible fluorescence. Infrared detection
gives you the quantitative analysis and wide linear dynamic
range that chemiluminescence cannot.
Strong and weak bands on the same blot are accurately
detected without the uncertainty and inconvenience of
multiple exposures, and without spending time in the
darkroom. The Odyssey System gives you clear, sharp,
reproducible bands without fuzziness or “blowout”. Bands
hidden by overexposure with chemiluminescence are clear
in Odyssey images.

Serial dilutions (10 ng to < 1 pg) of purified human transferrin (Tf)
were used to assess Western sensitivity. The Odyssey System,
using infrared fluorescence detection, reproducibly detected 1.2
pg of Tf, while only 4.9 - 9.8 pg was detected with chemiluminescence. Infrared detection sensitivity was approximately 200-fold
greater than previous studies with visible fluorophores (Cy®3, Cy®5,

A dot blot assay was used to compare the linear ranges of chemiluminescent and infrared fluorescent detection. Dilutions of mouse antibody were
spotted as antigen, and detected with HRP- or IRDye infrared dye-labeled goat anti-mouse antibodies. Chemiluminescent data were collected
using ECL substrate and a CCD camera with varying exposures; the infrared image was obtained in a single scan with the Odyssey System. For a
30 minute chemiluminescent exposure, the data set was linear over a 250-fold range. In contrast, infrared detection displayed a quantitative linear
range greater than 4000-fold (3.6 orders of magnitude). A paper detailing this study can be downloaded at www.licor.com/chemiccd.
Multiplex Western Detection
The two infrared fluorescent detection channels of the Odyssey System enable simultaneous two-color target analysis
– an advantage that’s not available with chemiluminescent or radioactive methods. Two-color Western analysis makes
normalization easy and eliminates error introduced by stripping and reprobing or by comparison of separate blots. Superior image clarity and detail make it easier to detect subtle mobility shifts caused by protein modifications such as
phosphorylation.

Through the innovative use of infrared fluorescent labeled

In contrast, the dynamic enzymatic nature of chemiluminescence allows you to capture only a “snapshot” of the
enzymatic reaction and is highly dependent on timing and
exposure, limiting linear range and offering only qualitative
or semi-quantitative results. The accuracy and linearity of
the Odyssey System detection allows you to be confident

Two separate lasers and detectors simultaneously detect
both fluorescent signals. The optical system employs diode
lasers and solid-state detectors due to their long lifetimes
and very low maintenance requirements. Infrared laser
excitation outperforms systems that use white light and
filter wheels by delivering higher intensity excitation light
to the fluorophore. A variety of fluorescent dyes and stains
are compatible with the 685 and 785 nm excitation wavelengths of the Odyssey System’s two diode lasers. Spectral
overlap is minimized by the 100 nm separation of the two
detection channels, and optical filtering assures that each
detector measures fluorescence from only one of the infrared dyes.

Beams from solid-state 685 and 785 nm lasers (A) are focused to form an
excitation spot on the scanning surface. A microscope objective (B), focused
on the excitation spot, collects light from both fluorescing infrared dyes.
Light from the microscope objective is passed through a dichroic mirror (C)
that splits the light into two fluorescent signals. The fluorescent signals travel
through two independent optical paths and are focused on separate silicon
avalanche photodiodes (D) and detected. In this example, 700 nm fluorescence (IkappaB) is shown in red (E) and 800 nm fluorescence (Tubulin) is
shown in green (F). The two colors were imaged simultaneously in a single
scan and can be displayed separately or together in a single image (G).

In-Cell Western™ Assay
For Ratiometric Protein Analysis
The In-Cell Western is an immunocytochemical assay
performed in microplate format. Target-specific primary
antibodies and infrared-labeled secondary antibodies are
used to detect target proteins in fixed cells, and fluorescent
signal from each well is quantified. Accuracy is enhanced
and data are more meaningful because proteins are detected in their cellular context.

variabilities and artifacts caused by cell lysis. In-cell detection
can provide more relevant results than enzyme assays with
